Holding the domain lock is necessary since __domain_flush_pages traverses the device list, which is protected by the domain lock. The first patch in the series adds a completion right after an IOTLB flush in attach_device. _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
